Zero Waste Europe investigates CO2 emissions of reusable and single use take-away packaging; models suggest that switching to reuse results in less emissions for most packaging; includes number of rotations and return rates to reach breakeven point
Washington state Department of Ecology publishes list of seven new priority chemical groups for future regulatory scrutiny as part of the Safer Products for Washington program; includes lead, cadmium, and formaldehyde; earlier in 2024, Washington passed the strongest regulation on lead in cookware in the US
Report microplastics occur in lower airways of European citizens with the majority being fibers; evaluate microplastics indoor and outdoor exposure sources; work out established particle domains and paradigms can help predict toxicity of inhaled microplastic particles
Four recent studies assess microplastics: in human semen, heart, from baby food containers, and suitability of in vitro models to investigate human health effects; find microplastics in six out of ten semen samples, find impacts on semen quality; samples from cardiac surgery patients contain microplastics in heart and surrounding tissue; billions of nano- and microplastics released from plastic baby food containers; outline challenges and recommendation of studying plastic particles in vitro
Smithers conference covers global developments in food contact regulations and materials; speakers on day two review recent and upcoming changes to food packaging regulations in China, Japan, India, and Southeast Asia
Review summarizes per- and polyfluoroalkyl substances (PFAS) migration from paper food packaging into food and food simulants and identifies dietary exposure of PFAS as potential human health risk; study highlights need to further evaluate organophosphate esters (OPEs) and prohibited PFAS in paper and aluminum foil food packaging; scientists analyze and recommend extraction method to assess plasticizers in recycled paperboard
Scientific study reports that gut passages change polyethylene terephthalate (PET) microplastics morphology and alter human microbial colonic community composition; another study finds polyethylene (PE) microplastics to accumulate in the brain and induce autism spectrum disorder-like symptoms using a mouse model
Four studies investigate bisphenol (BP) migration from packaging, occurrence in foodstuff, and human urine; report BPA migration from Nigerian epoxy-coated cans into malt drinks; detect four bisphenols in packaged water and honey samples; find BPS in Canadian meat products from 2008 to 2020 suggesting BPS is not a recent phenomenon; measure higher bisphenol alternative levels in Belgian population in 2018 than 2015
Researchers expand list of known substances with characteristics linked to breast cancer by more than four-fold; many are in standard consumer products, including 189 in food contact according to FPF’s database on migrating and extractable food contact chemicals (FCCmigex); authors call for improved hazard identification methods, advocate for more comprehensive chemical testing, especially focusing on the mammary gland and broader range of chemicals
Diplomats from across the globe descended on Paris, France to continue developing the UN treaty on plastics pollution; Scientist’s Coalition for an Effective Plastics Treaty members spoke to delegates from every continent, representing 33% of the world’s population; UN secretariat will develop INC-2 synthesis report, create zero draft by INC-3; elements for intersessional work can be submitted until August 15, 2023; INC-3 in Nairobi, Kenya in November 2023
